The effects of preatreatment of 5-HT3 receptor agonist (m-chlorophenyl-biguanide, EA+mCLBG, n = 10) and antagonist (ondansetron, EA+ODSTN, n = 10) in the CIOA rat treated by 2 Hz EA (EA+DMSO, n = 10) assessed by TFL (a) and PPT (b). Pretreatment with DMSO, mCLBG, and ODSTN was performed 20 min before 2 Hz EA. #p < 0.05, **p < 0.01, ***p < 0.001: compared with EA+DMSO
